As smart agriculture is rapidly put into practice, the drawbacks of traditional agricultural machinery — reliance on manual driving, low operation accuracy and continuously rising labor costs — have become increasingly prominent. As a core carrier of embodied intelligent equipment for farmland, the agricultural unmanned ground vehicle integrates multi-sensor perception, autonomous navigation, motion control, operation execution and cloud dispatching technologies. It is reshaping field operation modes including tillage, seeding, plant protection and transportation. This session will start from the underlying technical principles, break down the technical architecture of agricultural unmanned ground vehicles, and analyze its differentiated industry advantages in modern agriculture.
The technical system of agricultural unmanned ground vehicles consists of five modules: environmental perception, autonomous navigation and positioning, motion chassis control, operation execution unit and cloud platform coordination. The linkage of all modules enables unmanned autonomous operation.
Environmental perception serves as the “eyes” of the UGV. It is equipped with LiDAR, binocular vision cameras, millimeter-wave radars and ultrasonic sensors, together with environmental sensors for soil, temperature and humidity, to collect field information in real time. For complex scenarios such as orchards, greenhouses and irregular farmland, the sensor fusion algorithm can filter interferences caused by occlusion from branches and leaves, light changes and muddy ground. It identifies field ridges, obstacles and crop boundaries, outputs navigable areas and avoids collision risks.
Autonomous navigation and positioning is the technical core of the UGV, adopting a fusion solution of RTK high-precision Beidou positioning and inertial navigation. Beidou RTK delivers centimeter-level positioning, addressing the pain point that meter-level errors of ordinary GPS cannot meet the requirements of precision farming. Inertial navigation continuously outputs attitude and position data when satellite signals are blocked by fruit trees or greenhouse films, ensuring continuous positioning. Before operation, operators only need to survey plot boundaries with a handheld device. The system automatically generates operation routes and supports straight-line cruising, obstacle detouring, fixed-point return and multi-plot continuous operation without real-time manual control.
The motion chassis and power control system determine the field trafficability. Unlike industrial wheeled robots, the chassis of agricultural unmanned ground vehicles is off-road optimized. Both wheeled and tracked versions are available for different working conditions. It supports differential steering and in-place turning, and can adapt to sloped, muddy and bumpy farmland surfaces. The underlying motion controller receives navigation commands and adjusts vehicle speed and steering angle in real time. Combined with anti-slip power distribution, it prevents slipping and crop damage on wet soil. The matched operation actuators are modularly mountable, including plant protection spraying systems, fertilizer spreading units, and cargo bins for picking and transportation. One single unit can perform multiple farming tasks by switching different tooling.
The cloud dispatching platform acts as the “brain” to realize multi-vehicle collaboration and data accumulation. Multiple agricultural UGVs can operate in a network. The platform allocates field plots, monitors equipment status, and records working area, chemical consumption and operation tracks. Operation data is archived synchronously to build digital plot files, providing data support for variable-rate fertilization and precision plant protection. It truly realizes the transformation from experience-based farming to data-driven smart planting.
Compared with traditional agricultural machinery and manual labor, agricultural unmanned ground vehicles boast remarkable industry advantages. First, cost reduction and efficiency improvement. A single UGV can operate non stop for 24 hours, free from the constraints of day-night cycles and high temperatures. It greatly cuts the demand for tractor operators and eases the shortage and aging of rural agricultural labor.
Second, precise and controllable operation. Variable-rate spraying technology enables differentiated pesticide and fertilizer application according to crop growth conditions, cutting waste of agrochemicals and mitigating agricultural non-point source pollution, which aligns with the development requirements of green agriculture.
Third, strong scene adaptability. It is suitable for open farmland, orchards, greenhouses and plots for special cash crops. The modular design reduces farmers’ repeated procurement costs.
Fourth, standardized operation. Fixed routes and uniform spraying avoid missed or overlapping spraying caused by manual work, stabilizing the quality of farming operations.
Smart agriculture is now at a window for large-scale deployment. Agricultural UGVs are no longer laboratory prototypes; they have been deployed in batches for orchard plant protection, open-field transportation and protected agriculture. With continuous algorithm iteration and gradual equipment cost reduction, agricultural unmanned ground vehicles will become an essential part of modern agricultural infrastructure. They help improve output quality, cut costs and promote green agricultural production, and deliver sustained technological momentum for rural revitalization and agricultural modernization.
